Practice Practice Practice!
It's a strategy in itself.
It seems like you have a good grasp on the material (judging from the fact that you are scoring high on the test under less strict conditions). I'm hopeful that going to the class, and learning a few more time managed techniques will help you do well when it counts most.
I'm taking Blueprint in April, and I'm expecting that all the practice material they provide will force me to gain familiarity with every type of question to help me move faster through the test (with better accuracy of course). Even just to be able to make educated guesses on those last few questions per section would be nice.
In the meantime, I'm trying to review a few questions I've gone through already and explain how/why I chose the answer that I did. If I go through the process of figuring them out enough times, maybe I can come across a faster way, more efficient way of getting to it.
Let rigorous practice be the technology advancing you into the school of your choice
